RELATED APPLICATIONS

[0001] This application is a continuation in part of U.S. Ser. No. 10/105,599 filed Mar. 25, 2002.

FIELD OF INVENTION

[0002] The present invention relates generally to the field of tyrosine kinase enzyme inhibition using novel small molecules.

BACKGROUND OF THE INVENTION

[0003] Tyrosine Kinases are a class of enzymes, which catalyze the transfer of the terminal phosphate of adenosine triphosphate to the phenolic hydroxyl group of a tyrosine residue present in the target protein. Tyrosine kinases play a critical role in signal transduction for several cellular functions including cell proliferation, carcinogenesis, apoptosis, and cell differentiation (Plowman, G. D.; Ullrich, A.; Shawver, L. K.: Receptor Tyrosine Kinases As Targets For Drug Intervention. DN&P (1994) 7: 334-339). Therefore inhibitors of these enzymes would be useful for the treatment or prevention of proliferative diseases which are dependent on these enzymes. Strong epidemiologic evidence suggests that the overexpression or activation of receptor protein tyrosine kinases leading to constitutive mitogenic signaling is an important factor in a growing number of human malignancies. Tyrosine kinases that have been implicated in these processes include Abl, CDK's, EGF, EMT, FGF, FAK, Flk-1/KDR, HER-2, IGF-IR, IR, LCK, MET, PDGF, Src, and VEGF (Traxler, P. M. Protein Tyrosine Kinase Inhibitors in Cancer Treatment. Exp. Opin. Ther. Patents (1997) 7: 571-588; incorporated herein by reference). Hence, there is an ongoing need to investigate novel compounds that can be used to regulate or inhibit tyrosine kinase enzymes.

SUMMARY OF THE INVENTION

[0004] The present invention relates to compounds which inhibit tyrosine kinase enzymes, compositions which contain tyrosine kinase inhibiting compounds and methods of using inhibitors of tyrosine kinase enzymes to treat diseases which are characterized by an overexpression or upregulation of tyrosine kinase activity such as cancer, diabetes, restenosis, arteriosclerosis, psoriasis, angiogenic diseases and immunologic disorders (Powis, G.; Workman, P.

[0141] The invention further provides a method for treating proliferative diseases, comprising administering to a mammalian species in need of such treatment a therapeutically effective amount of at least one of the pharmaceutical compositions defined above.

[0142] Certain compounds of formula I may generally be prepared according to the following schemes and the knowledge of one skilled in the art. Solvates (e.g., hydrates) of the compounds of formula I are also within the scope of the present invention. Methods of solvation are generally known in the art. Accordingly, the compounds of the instant invention may be in the free or hydrate form, and may be obtained by methods exemplified by the following schemes below.

[0143] More specifically, Schemes I-VII illustrate the preparation of compounds claimed in this invention. The examples, which follow, illustrate the compounds that can be synthesized by these schemes. The schemes are not limited by the examples listed or by any substituents employed for illustrative purposes.

[0144] Scheme I describes the preparation of the benzimidazoles. The starting diamines 1 are readily available using literature methods or are obtained commercially. The diamine is then condensed with an aldehyde 2 to provide the benzimidazole 3. Further modification of the functional groups on the aryl group of the benzimidazole or heterocycle of 3 are then envisioned.

[0145] Alternatively, the benzimidazole could be formed in a step-wise manner (see Scheme II) by amide formation using the acid chloride of 5 or any of the commonly used peptide coupling reagents such as DCC (dicyclohexylcarbodiimide), EDCI (1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride), etc. Once the amide 6 was formed the nitro group could be reduced using catalytic hydrogenation, transfer hydrogenation or chemical reduction such as SnCl₂ or iron powder or other methods known in the art for reduction of aryl nitro groups. Treatment of the aniline with acid would then form the benzimidazole.

[0146] For example, Scheme III illustrates the use of 4-iodo-2-methoxy-pyridine-3-carbaldehyde 7 to provide the functionalized benzimidazole 8. Hydrolysis of the methoxy group using protic acid conditions, TMSI (trimethylsilyl iodide), BBr₃, or other conditions known in the art for cleaving a methyl ether would provide the halopyridone 9. Addition of heteroatom nucleophiles using amines, alcohols or thiols would then provide the substituted pyridones 10. Other functionality could be incorporated into the aldehyde and the above example is included for illustrative purposes only.

[0147] Likewise the aryl ring of the benzimidazole prepared using Schemes I or II can be modified. For example introduction of a cyano group for R³ on the benzimidazole allows for the formation of heterocycles such as imidazole, imidazolines, oxazolines, thiazolines, amides, or amidines. Scheme IV illustrates such transformations. Starting from the cyano-substituted benzimidazole 11 the heterocycle can be modified as illustrated in Scheme IV to provide 12. Imidate formation preferably using ethanol and acid provides intermediate 13. Imidate 13 can be transformed using diamines to form imidazolines, amino alcohols to form oxazolines, amino acetals to form imidazoles, and amino thiols to form thiazolines 14. Alternatively the imidate can be hydrolyzed to the acid and coupled with amines using any of the standard amide formation reagents (DCC, EDCI, etc.) to form amides 15. Imidate 13 is also a useful intermediate for the preparation of amidines 16 by reacting with amines.

[0148] Scheme V illustrates further transformation of benzimidazoles that bear a halogen atom using palladium catalysis using conditions developed by Suzuki [Yang et al. Acta Chem. Scand. (1993) 221; Suzuki et al. Synth. Commun. (1981) 11: 513] or Buchwald/Hartwig [Buchwald et al. J. Am. Chem. Soc. (1994) 116: 7901; Hartwig et al. J. Am. Chem. Soc. (1994) 116: 5969; Hartwig. Angew. Chem., Int. Ed. Engl. (1998) 37: 2046] and variations of these methods. Preparation of a bromide substituted benzimidazole 17 could be envisioned to provide a substrate for Suzuki coupling with aryl, vinyl, and heterocyclic boronic acids to provide benzimidazoles 18. Likewise, amines and heterocycles such as piperazine or morpholine derivatives 19 can be prepared from the same bromide using amines under conditions described by Buchwald and Hartwig or variations thereof.

[0149] Alternatively amine and heterocyclic derivatives such as 19 can be prepared using intermediate 6 described in Scheme II. When the R³ of 6 is a halogen, preferably F, the halogen can be displaced with amines, alcohols, heterocyclic amines and other nitrogen containing heterocycles such as piperazine, piperidine, 4-amino piperidine, morpholine, imidazole, etc (Scheme VI). The terminal nitrogen of piperazine or 4-amino piperidine can then be alkylated using standard alkylation conditions or reacted with aldehydes in a reductive amination reaction to provide alkylated derivatives. Alternatively the terminal nitrogen atom of piperazine or 4-amino piperidine can be acylated or carbamoylated using any number of conditions that are routine for someone skilled in the art of organic synthesis. Following the example illustrated in Scheme II compounds such as 19 could be prepared.

[0150] Alternatively amines, heterocycles, and alcohols can be introduced at R₃ using a nucleophilic aromatic substitution reaction started from an intermediate 20 were R₃ is halogen, preferably F, the halogen can be displaced with amines, alcohols, heterocyclic amines and other nitrogen containing heterocycles such as piperazine, piperidine, 4-amino piperidine, morpholine, imidazole, etc (Scheme VII). The terminal nitrogen of piperazine or 4-amino piperidine can then be alkylated using standard alkylation conditions or reacted with aldehydes in a reductive amination reaction to provide alkylated derivatives. Alternatively the terminal nitrogen atom of piperazine or 4-amino piperidine can be acylated or carbamoylated using any number of conditions that are routine for someone skilled in the art of organic synthesis. The resulting nitro aniline could be reduced to the diamine 21 and processed as illustrated in Scheme III.

[0163] Compounds of formula I may also be useful in the chemoprevention of cancer. Chemoprevention is defined as inhibiting the development of invasive cancer by either blocking the initiating mutagenic event or by blocking the progression of pre-malignant cells that have already suffered an insult or inhibiting tumor relapse.

[0164] Compounds of formula I may also be useful in inhibiting tumor angiogenesis and metastasis.

[0165] The compounds of this invention may also be useful in combination (administered together or sequentially) with known anti-cancer treatments such as radiation therapy or with cytostatic or cytotoxic agents, such as for example, but not limited to, DNA interactive agents, such as cisplatin or doxorubicin; topoisomerase II inhibitors, such as etoposide; topoisomerase I inhibitors such as CPT- 11 or topotecan; tubulin interacting agents, such as paclitaxel, docetaxel or the epothilones; hormonal agents, such as tamoxifen; thymidilate synthase inhibitors, such as 5-fluorouracil; and anti-metabolites, such as methotrexate; tyrosine kinase inhibitors such as Iressa and OSI-774 (Tarceva™); Avastin, Herceptin, angiogenesis inhibitors; EGF inhibitors; VEGF inhibitors; CDK inhibitors; Her1/2 inhibitors and monoclonal antibodies directed against growth factor receptors such as erbitux (EGF) and herceptin (Her2).

Fluorine Chem., 43, (1989), 371-377) and the mixture heated to 80° C. for 3 h. The reaction mixture was then purified on reverse phase preparative HPLC using a methanol/water/0.1% trifluoroacetic acid gradient. The fractions were evaporated to give the title compound as a trifluoroacetic acid salt, which was dissolved in methanol and applied to a Varian Mega Bond-Elute SCX cartridge. Elution with methanol followed by 2.0 M NH3/MeOH gave the free base (35.9 mg). This material was suspended in MeOH and 1.00 N aqueous HCI (2 equiv.) was added. The resulting solution was filtered through a 45 μm filter and evaporated to give the bis HCl salt of the title compound (37.6 mg): ¹H NMR (400 MHz, CD₃OD) δ 7.61 (brs, 1H), 7.47 (brs, 1H), 7.44-7.20 (m, 5H), 6.27 (d, 1H, J=7.6 Hz), 4.92 (dd, 1H, J=4.4, 7.3 Hz), 4.50 (dt, 2H, J=5,9, 47.3 Hz), 4.05-3.40 (m, 10H), 2.64 (s, 3H), 2.63 (t, 2H, J=7.6 Hz), 2.09-1.95 (m, 2H); LCMS (M+H)⁺ m/z 567,569.

[0608] General procedure for preparation of mono- and bis-HCl salts: A solution or suspension of free base in methanol is treated with 1.00 (or 2.00 resp.) equivalent of 1.00 N aqueous HCl. If significant amounts of compound remain insoluble an equal volume of dichlorethane is added to improve solubility. The mixture is filtered and concentrated in vacuo. Small amounts were evaporate to dryness, large-scale preparations for in vivo studies were concentrated until most of the compound crystallized, then filtered.
